  • Complete renovation of the Zug cantonal school

    Complete renovation of the Zug cantonal school

    The Zug Cantonal School, a masterpiece of post-war modernism, was designed between 1971 and 1975 by the renowned architects Leo Hafner and Alfons Wiederkehr. The exterior design by Fred Eicher is also an integral part of this architectural heritage. In view of the advancing structural ageing, there is an urgent need for comprehensive renovation measures. These include upgrading the load-bearing structure, replacing the building envelope and replacing the building services and interior fittings. In particular, the focus on adapting the room structure is crucial in order to guarantee learning conditions.

    Refurbishment concept and targeted extension
    The refurbishment concept, which was developed in close cooperation with the school management, offers a balanced solution between the needs of flexible teaching methods and the existing spatial conditions. The available space will be expanded in a targeted manner through clever room renovations and adaptations. Planned measures include a new connecting wing and an extension to Wing 7 in order to meet the challenges of modern educational requirements.

    Principles of sustainability
    The decision in favor of a complete renovation is based on the financial, ecological and scheduling advantages. The Construction Department of the Canton of Zug is thus pursuing its clear real estate strategy. New construction projects should only be considered if it is no longer possible to optimize the existing buildings.

    Project competition and next steps
    The next milestone in the renovation process is the project competition in a selective procedure, which was announced in mid-2024 and is aimed at general planning teams. The aim is to find the best solutions for a renovation that respects the preservation of the original architecture while meeting the requirements of a modern educational establishment. The Construction Department of the Canton of Zug emphasizes that the competition represents a decisive phase in the implementation of the project and should ensure a high-quality renovation.

  • Bern plans to revitalise the Historical Museum

    Bern plans to revitalise the Historical Museum

    The Bern Historical Museum, which is over 130 years old, is about to undergo extensive modernisation and expansion. Following a thorough examination, the Education Commission has recognised the need for comprehensive modernisation and strategic expansion and recommends that the Grand Council approve the project planning credit of CHF 2.5 million. This step is important in order to press ahead with the detailed planning and cost estimates for the refurbishment, extension and integration into the newly designed Museumsquartier Bern.

    The Museum’s Board of Trustees has already set the course for a comprehensive renovation, which envisages both a complete refurbishment of the existing historic building and a modern extension. The planned extension is intended to improve accessibility, open up the museum garden and integrate it into the museum quarter. The new building will also make the museum barrier-free and support modern exhibition concepts.

    The Burgergemeinde Bern has already approved a loan of the same amount, and the City of Bern is expected to make its decision later this year. The Education Commission emphasises the advantages of the project, which will not only improve the museum’s infrastructure, but also increase the attractiveness of the site for visitors and open up new opportunities for cultural events and special projects.

    The approval of the project planning credit by the Grand Council is an important milestone for the project, which promises significant added value for the cultural landscape of the canton and the city of Bern. Following approval by the Grand Council and subsequent approval by the electorate, planning work should begin in autumn 2024, with the new museum building scheduled to open in summer 2027.

  • Jaisli-Xamax is working on the Vechigen school complex

    Jaisli-Xamax is working on the Vechigen school complex

    The electrical company Jaisli-Xamax from Dietikon carries out all electrical installations for the overall renovation and expansion of the Stämpbach school complex in Vechigen. According to a report in the employee newspaper Brilli's News , the work will be carried out during the three implementation phases while the school is still running. “One of the challenges was to carry out the work while the school was still in operation,” the construction fitter Adrian Thürig is quoted as saying. Nevertheless, it was possible to "produce a clean performance".

    The work will be carried out in three stages. According to Jaisli-Xamax, the new construction of the kindergarten, the day school, the special wing and the intermediate wing as well as the renovation of the two gyms were realized in the first construction phase. The renovation of the east class wing and the expansion of the group rooms were implemented in the second construction phase. The work on the third construction phase is still ongoing. The West class wing will be renovated.

    According to project manager Luciano Matturro from Jaisli-Xamax, the cooperation with everyone involved in the construction and with the school went smoothly. Matturro was quoted as saying that he was proud that the on-site team did its job well while the school was in operation. Matturro: “We are now on the final spurt to successfully complete the third construction phase.” Two apprentices from Jaisli-Xamax also worked on the project in the canton of Bern.

  • Complete renovation of the Olten Cantonal School

    Complete renovation of the Olten Cantonal School

    Work at the canton school in Olten has been going on for five years. Around 1000 pupils are taught at the school, which was completed in 1973 by the architects Marc Funk and Hans-Ulrich Fuhrimann. Construction work is ongoing in parallel. The architectural office Batimo AG Architekten SIA from Olten, which specializes in renovation strategies and has already renovated numerous school buildings, was commissioned.

    "In order not to impair school operations too much, we have postponed the most noisy work to the school holidays according to specifications and in consultation with the school management," explains Dario Pagliari – he is responsible for construction management on the part of Batimo AG. The overall renovation includes a complete renovation of the building services and the facade, slight floor plan adjustments, the elimination of technical defects and an adjustment to the current standard in terms of fire protection, earthquake safety and energy efficiency.

    Great attention is then also paid to improved energy efficiency: the modified building envelope, an optimized, natural ventilation concept as well as a geothermal heat pump system and the installation of a solar system reduce the energy consumption of the buildings by around 67 percent. The annual CO2 emissions are reduced by 732 tons, which translates into annual energy cost savings of around 200,000 francs.

    The work was divided into different stages: "Right at the beginning we replaced the windows and carried out the insulation work both inside and on the flat roofs," explains Pagliari. The work on the indoor swimming pool, the cafeteria, the auditorium as well as the workrooms and gyms have already been completed. The premises are currently being adapted to the changing needs of school operations, as the site manager explains. A floor can be renovated in a three-month stage. The pupils of the corresponding classes are meanwhile being taught in the specially built temporary school facility with eight classrooms. There are a total of two school wings with ten and five floors each.

    The last stage will include work on the surrounding area as well as the renovation of the sports fields and underground car park. Once all the work has been completed, the Olten Cantonal School should be fit for another 40 years of operation at its special location in the elevated forest area not far from the train station.
